Effects of changes in species composition and distribution on contaminant food web accumulation
pi_name: Katrine Borgå
Abstract
Work description As changes in temperature and sea ice distribution and thickness is expected in the region of interest, the energy transfer processes in the food web are expected to be changed compared to previous decades. Zooplankton and fish samples will be collected focusing on the process study cruises. From these, chemicals representing lipid soluble and protein associated contaminants will be analyzed, in addition to dietary descriptors to trace energy source (stable isotopes and lipid analyses). This will be repeated in the different seasons to interpret the annual dynamics of contaminant accumulation and transfer in the food web related to energy use and availability. So far, seasonal food web data are only available from Arctic fjords. At the UiO stable isotope lab, we will measure bulk C, H, N, O and S in organic material, and thus the ratios between lipid/protein/carbohydrate will be analyzed in small amounts of sample without extraction to assess the proximate biochemical composition. Model predictions of climate change effect on food web accumulation of contaminants include reduced accumulation due to predicted reduction in lipid storage. Bioaccumulation changes due to altered dietary composition is predicted to have less influence than the predicted lower lipid content. These predictions will be tested in the present task. A similar approach of sampling the central Barents Sea pelagic food web was taken in May 1998 (however, only with bulk stable isotope analyses of 13C and 15N), which allows a thorough comparison between the environmental states two decades apart. (From Nansen Legacy implementation plan)

T2-2.5 Critical seasonal windows of responses to multiple stressors on key organisms of benthic and pelagic food chains
pi_name: Oystein Varpe
Abstract
Due to climate change and pollution Arctic ecosystems are exposed to multiple stressors. Arctic ecosystems are highly seasonal and include substantial changes in the lipid composition of the organisms throughout the year. In periods with lipid mobilization many marine species will be prone to external stressors which may influence their ecology, physiology and biochemistry. These “critical periods of effects” (when energy stores are depleted and pollutants are remobilized from lipids to blood and other body organs) need to be determined in Arctic species belonging to the benthic and pelagic food chain. Key species in the benthic (amphipods, bivalves and common eiders) and pelagic (macrozooplankton, polar cod and kittiwakes) food web will be sampled throughout the year, with seabird data primarily from collaboration with ongoing and NPI lead work in breeding colonies. For fish and birds, organ specific distributions of pollutants and organ specific annual composition of fat, protein and energy will be quantified to determine their critical periods of effects in relation to time of year. From this, combined with habitat use and activity levels, critical periods of effects can be predicted.

Seasonality in primary production, Nitrogen sources for primary production and primary producers response to light intensity
pi_name: Rolf Gradinger
Abstract
Several functional aspects of pelagic and simpagic primary producers were studied during the Nansen Legacy Q3 cruise. In open water stations (P1, P4, P5), water was sampled from the standard depths 10, 20, 40, 60, 90 and Chl a max. Water from these depths was spiked with radioactively labelled carbon in order to determine to the Carbon fixation rate (i.e. the Primary Production rate) of phototrophic organisms throughout the water column and latitudinal gradient. Additionally, water from 10m and Chla max was spiked with stable isotopes of Carbon (13C) and Nitrogen (15N) to determine the F-ratio (which fraction of the estimated primary production is new production). One incubation bottle was also treated to assess the nitrification activity of microbes. These incubations were deployed attached to the sediment trap moorings and exposed to in situ light and temperature conditions for 24 hours. In parallel, water from the Chla max was used to determine the photosynthetic response of the community to light intensity (P vs I curves). At the ice-covered stations (P6 and P7), the aforementioned water sampling and experimental work was carried as described, and additionally the bottom 3cm of 4 ice cores were sampled and pooled for similar in situ incubations: Under-ice Primary production, Nitrogen uptake and PvsI curve. Water from a meltpond was sampled, spiked and incubated in situ for Primary Production and Nitrogen uptake. A reciprocal transplant experiment was conducted with surface water from stations P1 and P6 and will be analyzed for abundance and community shifts due to changes in environmental factors.
